Neural network-based multipartite entanglement classification with prior guidance from quantum uncertainty relations
Qiyi Li, Xiao Zheng, Guofeng Zhang
Quantum entanglement is a crucial resource in quantum information processing, yet its efficient, scalable and robust classification in multipartite systems remains theoretically ch…
Dynamics Investigation of the quantum-control-assisted multipartite uncertainty relation in Heisenberg model with Dzyaloshinski-Moriya interaction
Jie Xu, Xiao Zheng, Ai-Ling Ji +1
Recently, Zheng constructs a quantum-control-assisted multipartite variance-based uncertainty relation, which successfully extends the conditional uncertainty relation to the multi…
Stronger Reverse Uncertainty Relation for Multiple Incompatible Observables
Xiao Zheng, Ai-Ling Ji, Guo-Feng Zhang
Recently,D.Mondal et.al[Phys. Rev. A. 95, 052117(2017)]creatively introduce a new interesting concept of reverse uncertainty relation which indicates that one cannot only prepare q…
Multi-observable Uncertainty Equality based on the sum of standard deviations in the qubit system
Xiao Zheng, Shaoqiang Ma, Guofeng Zhang
We construct a multi-observable uncertainty equality as well as an inequality based on the sum of standard deviations in the qubit system. The obtained equality indicates that the…
Phase Anti-Synchronization dynamics between Mechanical Oscillator and Atomic Ensemble within a Fabry-Perot Cavity
Shao-Qiang Ma, Xiao Zheng, Guo-Feng Zhang
Phase synchronization refers to a kind of collective phenomenon that the phase difference between two or more systems is locked, and it has widely been investigated between systems…
Criterion of Quantum Phase Synchronization in Continuous Variable Systems by Local Measurement
Shao-Qiang Ma, Xiao Zheng, Guo-Feng Zhang
Phase synchronization was proved to be unbounded in quantum level, but the witness of phase synchronization is always expensive in terms of the quantum resource and non-local measu…
